| Abstract: | Interaction between aqueous dispersion of anionic polyurethane and gelatin was investigated by UV and FTIR spectrometry.A complex formed by Coulomb forces was found in the solution around pH4 6.The influences of weight ratio,pH values,temperature and electrolyte on the mixed system were studied,and parameters(such as temperature,ionic strength)have a considerable impact on the formation of compleies as well.H bond played a part role in the compatibility of the mixed system.The best compatibility was attained in the mixed system at weight ratio 50/50～40/60(gelatin/APU). |
